The HI98129 and HI98130 are waterproof testers that offer high accuracy pH, EC/TDS, and temperature measurements in a single tester; no more switching between meters for your routine measurements. These floating, waterproof combination testers have an easy-to-read LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature-compensated.
These testers feature a replaceable pH electrode cartridge with an extendable cloth junction, as well as an EC/TDS graphite electrode. The renewable cloth junction provides an extended electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted.
The EC/TDS conversion factor is user selectable, as well as the temperature compensation coefficient (β). Fast, efficient, accurate, and portable, the Combo pH, EC/TDS, and temperature testers combine all the features users have requested and more!
High Accuracy EC/TDS Graphite:
The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution. The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings.
Replaceable pH Electrode Cartridge:
The Combo features an easy-to-replace pH electrode. The sturdy, snap-in connector means there are no pins to bend or break.
Extendable Cloth Junction:
Simply pull out 3 mm (1/8”) and cut when the cloth junction becomes dirty to improve response time and stability.
- Designed to float if accidentally dropped in a tank
- Automatic Temperature Compensation
- All readings are compensated for variations in temperature
- Temperature displayed in °C or °F along with pH reading
- Stability indicator Meter displays a clock tag that will disappear when the reading has achieved stability
- HOLD button Freezes reading on the display to allow recording of measurement
- BEPS (Battery Error Prevention System) Meter will automatically shut off if there is not enough power to get an accurate measurement
- Battery % level at startup
- Low Battery Indicator
- Automatically shuts off after 8 minutes of non-use to maximize battery life
